We studied the content of Cadmium, Lead, Strontium and Nickel in the biological systems: environment – feed – animal – livestock products in agroecological conditions of Zacarpathian region. It is noted that the content of Cadmium and Strontium in soil samples taken from commercial land PAL «Lastochka», Uzhgorod district, Zacarpathian region did not exceed the maximum allowable concentrations, whereas the levels of Lead and Nickel were higher. The content of investigated elements in water used for watering cows in farm was 0.02–1.02 mg/l and did not exceed the maximum allowable concentrations which is up to veterinary and sanitary requirements. It is known from the literary sources that there is interdependency between the heavy metals level in soil and their accumulation in farming cultures. The obtained results of the study of heavy metals in feed (hay, straw, wheat, mixed fodder) harvested on the farm did not exceed the maximum allowable concentrations of studied elements in feed rations for animals. It is known that heavy metals in fodder transform in animal organism and have influence on the intensity of metabolic processes, physiological and biochemical condition and animal productivity. Concentrations of the elements in cows’ whole blood and hair were within physiological values. Absolute content of Cadmium, Lead, Strontium and Nickel in the milk of studied cows were under 0.014; 0.02; 0.15 and 0.2 mg/kg, respectively and did not exceed the maximum allowable concentrations.The analysis of coefficient of correlation between the heavy metals content in biological systems: environment – feed – animal – livestock products revealed the strong correlation between the heavy metals content in soil and water, in straw and mixed fodder, in blood, hair and milk, and the poorly expressed correlation between their content in catena: water – straw – blood – milk.

The paper presents data on the content of gross and mobile forms of zinc, cadmium, lead and copper in the soils of Chita and its surroundings. The paper contains a comparative analysis of the accumulation (Kn) and movement (KP) coefficients of these microelements in organs ( Potentilla tanacetifolia Willd. ex Schlecht.), relative to their gross content and mobile forms in soils. The authors have revealed that soil samples of the studied sites contain unequal gross amount of heavy metals. In some points (6 and 3) the content of cadmium and zinc exceeded the Mac, that is why such soils have been attributed to heavily polluted. The index of biological activity on mobile forms of heavy metals in all sites significantly exceeded the same index on gross forms. It was found that Potentilla tanacetifolia are accumulators of heavy metal ions. Aboveground bodies accumulate and absorb cadmium and copper especially intensively, thus the content of mobile forms of these metals in the soil is insignificant. Excessive adsorption of trace elements in the phytomass of plants can be connected with surface contamination. According to the content of zinc and lead, the accumulation values in the organs of P. tanacetifolia were characterized by small coefficient values, against the background of their high concentration in the soil.

The aim of the study. To assess the contamination of the soil cover of the St. Petersburg State University campus. To accomplish the goal, tasks are set concerning the determination of the content of heavy metals in selected soil samples and their comparison with the available regulatory documents, estimates of the basal respiration of the soil and humus content. Materials and methods. In 2016-2017 there were executed investigations on the study of the state of soils on the campus of the St. Petersburg State University. Studies were carried out in the Vasileostrovsky and Petrodvorets districts of the city of St. Petersburg. 39 soil samples were taken from a depth of 0-30 cm. The content values of heavy metals (Pb, As, Zn, Cu, Ni, Co, Cr, V) and arsenic (As) were determined and compared with the available Maximum Allowable Concentrations (MAC) adopted in Russia. The biological activity of soil samples and the humus content were also investigated. Results. Analysis of heavy metals in soils and their comparison with available MPCs are given for soil samples from two campus areas of the St. Petersburg State University. Discussion. The investigation of soil samples of two different territories made it possible to identify the features of soil contamination with heavy metals and arsenic and to compare these areas with each other. The predominant majority of samples are characterized by exceeding the MAC limit for arsenic, zinc, nickel, chromium. To clarify the estimation of the levels of total contamination of soils, Zc, also Zst(g) were used in these calculations. Zst(g) takes into account the geometric mean of the concentration coefficients of elements and the toxicity of heavy elements Conclusion. Samples of soils selected in the Vasileostrovsky district are characterized by a higher pollution category in terms of Zc and Zst(g) than the soils of the Petrodvorets district. For all soil samples, the value of soil pollution index is more than 1, which characterizes the soils as contaminated. The indices of the microbiological activity are similar in the soils of the two investigated areas; the humus content is characterized as an average also in both campus areas.

Investigations were carried out to study the state of the soil in the territory of the Shetpe South chalk deposit and in the area of the Caspian Cement plant in October 2018. 20 soil samples were taken. Samples were taken from a depth of 0–20 cm. The presence of heavy metals in the soil was determined by atomic absorption spectrometry using AAC MGA-915M (Lumex, Russia), their content was compared with background values and with existing maximum allowable concentrations. The total soil pollution indicator or ZC , using the background, was used to study the state of the soil. The indicators of the soil pollution index were calculated to improve the diagnostic performance of the study area. The calculation of the total soil pollution indicator showed that the value of ZC for all sites was from 3,58 to 5,26 units. The soils are characterized as non-hazardous (ZC < 16), and the assessment of the condition of the soil is biased due to taking into account only heavy metals with KC < 1. The soil pollution index calculations showed that the majority of soil samples at sites PP-1, PP-2 and PP-3 have indicators of soil pollution index > 1, which characterizes the soil as "polluted". At site PP-4 (control) the soil pollution index is 0,74, the soils are "clean". Statistical processing in the environment Statistica 10 showed that the Kruskal — Wallis criterion is statistically significant only for Ni and As (p < 0,05) for soil samples at site PP-2 (at the site of transportation of chalk and dumps). Maps were performed using satellite imagery and using of Google Maps, Mapinfo Professionalv. 12.

The soil in the vicinity of stream of Buddah Nullah in Ludhiana, Punjab has been found to be contaminated with heavy metals. The objective of this paper was to conduct studies with earthworm Eisenia fetida (Savigny) exposed to five soil samples collected from different sites around the stream of Buddah Nullah, since no such work has been done using earthworm as bio- indicator of soil pollution in that area to check the hazardous effects of heavy metals on soil organisms. Metal levels were recorded higher in contaminated soil samples than threshold concentration in soil of campus field. Adult E. fetida were exposed for a period of 80 days to evaluate the effects of elevated levels of heavy metals i.e.0.29 ppm, 4.18 ppm and 2.29 ppm for cadmium, lead and nickel respectively on survival, growth, morphology and reproduction. Significant effects were observed on survival, growth and reproduction of the tested organisms along with various morphological abnormalities such as tail shedding, body fragmentation and extrusion of coelomic fluid. But no such deformity was observed in worms reared in reference soil of university campus field. Detrimental effects on rates of cocoon production and hatchling emergence were observed and a significant delay was also recorded in production of cocoons and emergence of hatchlings. Results of the study indicated that reproductive end points were more sensitive to elevated metal levels in contaminated soil than survival or weight change.

The article focuses on the study of change of containing heavy metals (zinc, copper, iron, cadmium, lead, arsenic) in the abiotic and biotic components of the Serepok river (Vietman) influenced by wastewater discharge from industrial areas. Heavy metal content was determined in the river water and bottom sediments in the four zones: above and within the boundaries of industrial regions Xoa Phu and Tam Thang and in two water reservoirs situated below the boundaries of those industrial areas. Tilapia Galilean ( Sarotherodon galilaeus ), Hemibagrus ( Hemibagrus ), and sazan ( Cyprinus carpio ) caught in these areas were the hydrobionts under study in which liver, gills, skeleton and muscles accumulation of heavy metals was detected. In the organs of fish caught in the river within industrial region, heavy metals concentration was 3-7 times higher. The greatest concentration of heavy metals was found in the liver and gills of fish caught in the boundaries of industrial regions, the least concentration was in the muscles. In most cases, significant correlation between heavy metal concentration in organs of fishes and in river water, bottom sediments has been revealed.

Heavy metals are primarily generated and deposited in the environment, causing phytotoxicity. This work evaluated fenugreek plants’ morpho-physiological and biochemical responses under mercury stress conditions toward Ag nanoparticles and Sphingobacterium ginsenosidiumtans applications. The fabrication of Ag nanoparticles by Thymus vulgaris was monitored and described by UV/Vis analysis, FTIR, and SEM. The effect of mercury on vegetative growth was determined by measuring the root and shoots length, the number and area of leaves, the relative water content, and the weight of the green and dried plants; appraisal of photosynthetic pigments, proline, hydrogen peroxide, and total phenols content were also performed. In addition, the manipulation of Ag nanoparticles, S. ginsenosidiumtans, and their combination were tested for mercury stress. Here, Ag nanoparticles were formed at 420 nm with a uniform cuboid form and size of 85 nm. Interestingly, the gradual suppression of vegetal growth and photosynthetic pigments by mercury, Ag nanoparticles, and S. ginsenosidiumtans were detected; however, carotenoids and anthocyanins were significantly increased. In addition, proline, hydrogen peroxide, and total phenols content were significantly increased because mercury and S. ginsenosidiumtans enhance this increase. Ag nanoparticles achieve higher levels by the combination. Thus, S. ginsenosidiumtans and Ag nanoparticles could have the plausible ability to relieve and combat mercury’s dangerous effects in fenugreek.

In this study, the geochemical properties of heavy metal-contaminated soils from a Korean military shooting range were analyzed. The chemical behavior of heavy metals was determined by analyzing the soil pH, heavy metal concentration, mineral composition, and Pb isotopes. In total, 24 soil samples were collected from a Korean military shooting range. The soil samples consist of quartz, albite, microcline, muscovite/illite, kaolinite, chlorite, and calcite. Lead minerals, such as hydrocerussite and anglesite, which are indicative of a transformation into secondary mineral phases, were not observed. All soils were strongly contaminated with Pb with minor concentrations of Cu, Ni, Cd, and Zn. Arsenic was rarely detected. The obtained results are indicated that the soils from the shooting range are contaminated with heavy metals and have evidences of different degree of anthropogenic Pb sources. This study is crucial for the evaluation of heavy metal-contaminated soils in shooting ranges and their environmental effect as well as for the establishment of management strategies for the mitigation of environmental risks.
